Thread Subject: Getting mean, std, var and cov value of cell array

Hello, People
I just learn MATLAB and newbie. I have cell array like this
Name Size Bytes Class Attributes

  Yh 3x1 2064564 cell

<128x128x6 double>
<64x64x6 double>
<32x32x6 double>

I'm confusing in dimension and how to use this data to get values of mean, std and cov of Yh.
So, how to get this values?
Really appreciate for your help.
Thanks.

Hi Tirta, use cellfun(). See

>>doc cellfun

for example:

% Create a cell array with some data
Y = cell(2,1);
Y{1,1} = randn(10,10);
Y{2,1} = randn(10,1);
% Apply cellfun() to get mean and std
Meanz = cellfun(@mean,Y,'UniformOutput',false);
Stdz = cellfun(@std,Y,'UniformOutput',false);

Hope that helps,
